It could be you upgraded to IE8, offered automatically now through Windows Update, which has known compatibility issues. If you are using IE8, try uninstalling it, automatically reverting to IE6/IE7, and see if that resolves the problem.
Let us know.
Recently, websites with video requiring flashplayer tell me I need to install flashplayer. I have flashplayer10 installed. I've used the Adobe uninstaller and re-installed. The installed files seem to be there (in windows\sytem32\macromed) and the adobe install site said installation was successful. Websites still don't recognize FP. Also, at abc.com, their full episode player didn't recognize my Internet Explorer, saying it only worked with certain browsers, such as IE. Are these problems linked?
Any advice would be greatly appreciated.
